Answer:
<u>Standard deviation for owner-occupied units</u>
2.9797
<u>Standard deviation for renter-occupied units</u>
3.1594
Step-by-step explanation:
Let us find first the mean. This is the distribution expected value or expectancy.
<u>Mean for owner-occupied units</u>
0.003 + 2*0.002 + 3*0.023 + 4*0.102 + 5*0.209 + 6*0.223 + 7*0.201 + 8*0.149 + 9*0.053 + 10*0.035 = 6.293
To compute the variance for owner-occupied units, we add these values
then divide by 10 and take the square root to get the standard deviation 2.9797
<u>Mean for renter-occupied units</u>
0.008 + 2*0.027 + 3*0.287 + 4*0.371 + 5*0.155 + 6*0.090 + 7*0.043 + 8*0.013 + 9*0.003 + 10*0.003 = 4.184
To compute the variance for renter-occupied units, we add these values
then divide by 10 and take the square root to get the standard deviation 4.184
